【摘要】：随着畜禽养殖规模的不断增加和集约化养殖方式的快速发展,大量畜禽粪尿集中排放。挥发的氨气(NH3)不仅对环境造成巨大污染,同时也严重影响畜禽的健康,诱发各种疾病,导致生产性能下降。因此,分析畜禽的氨气排放规律及其对畜禽生产和健康的影响,对控制畜禽舍氨气浓度具有重要意义。本文主要阐述了畜禽舍氨气排放影响因素,以及氨气排放规律;分析了氨气对畜禽健康的影响及其对机体的损伤机理,为规模化畜禽生产提供参考。
[Abstract]:With the increasing scale of livestock and poultry breeding and the rapid development of intensive farming, a large number of livestock and poultry feces and urine concentrated emissions, volatile ammonia ammonia (NH3) not only caused great pollution to the environment. At the same time, it also seriously affects the health of livestock and poultry, induces various diseases, and results in the decline of production performance. Therefore, the regulation of ammonia emission and its effect on the production and health of livestock and poultry are analyzed. It is of great significance to control the concentration of ammonia gas in livestock and poultry houses. This paper mainly expounds the influencing factors of ammonia gas emission from livestock and poultry houses, as well as the rules of ammonia gas emission. The effects of ammonia gas on the health of livestock and poultry and the mechanism of its damage to the body were analyzed in order to provide reference for the large-scale production of livestock and poultry.

【正文快照】： 氨氮排放污染严重制约了我国畜禽养殖的可持续发展。以养猪业为例,猪只能利用饲料中30%~55%的氮,其余大部分以粪尿形式排出,而尿氮中97%的氮是以尿素的形式存在,育肥猪每天排放的氨气(NH3)约为70 g[1-2]。畜禽养殖产生的氮污染已经超过了单位面积的承载量[3],根据《“十三五”
